I am working to prepare for Azure AD Connect and running the IDFIX tools. It finds a bunch of errors because of my PROXY ADDRESSES with the CHARACTER issue. The problem is we have a bunch of exchange legacy DN set up in exchange with X500 addresses which include a space. ie in the address it has ou=Exchange Administrative Group within it from previous mergers we did with acquisitions. Anyone else face this issue? If you did, what did you do to overcome this issue?
